Private airport at a privately owned ski lodge, but they will allow any one who wishes to land there.
A fee for non customers of the lodge makes sense to me, and collecting with a camera is much cheaper than having an attendant on site 24/7. Cheapest price you will get for using a private, for profit airport. Fuel flow is not one of their driving financial flows.
I am opposed to landing fees in general, but this seems to be a reasonable exception.
Since the formation of the Free State Flying Club, in 1969, there has always been a landing fee at Washington National/Reagan National, but 3 members of the club have landed there, and paid no fee. I was the last one, landed at 3 AM, full stop, then departed the same runway without going to the FBO, who collects the fee.
Davis, a local Maryland, privately owned airport, open to the public, has a fee that is waived if you fill up with gas. The lady who owns it says that if you land you have to help pay to fill the potholes and cut the grass. Makes sense to me. There are very few resident planes paying tie downs fees.
